OpenAI's most recent private valuation stands at $852 billion following its record $122 billion funding round closed March 31, 2026, which incorporated commitments from major investors including SoftBank, Nvidia, and Amazon. With the June 30 resolution date now only days away, no new equity round, tender offer, or liquidity event has materialized to reset the post-money figure in the intervening period. Confidential IPO filings in late May point to a potential September debut at or above this level, yet that timeline sits well beyond the market's cutoff. Revenue run-rate growth and ongoing infrastructure spending continue to support the existing mark, while the absence of fresh capital raises or secondary transactions leaves limited scope for an upward revaluation before month-end.
